Snookie gets in a car accident, Ronnie knocks out The Situation, JWoww lookin’ good, Vinnie wants to become fluent in Italian (note: not happening). As you can imagine it didn’t take long for the Jersey Shore cast to turn beautiful Florence, Italy into a scene from Seaside Heights club, Karma. View trailer below.
